Element for composing a track of the fall type for run of marbles

Abstract

An element for composing a track of the fall type for run of marbles, which comprises a guide member for insertion of marbles to be placed beneath the arrival of a preceding track element or at the upper start point of a track, an exit guide member to be placed at a level lower than the level of the insertion guide member over the start end of a subsequent track element, and a track section extending in the form of a pair of rails from said insertion guide member to said exit guide member, by following at least in part a helicoidal trajectory. Preferably, this latter track section comprises a rectilinear section for approach to the helicoidal portion. The entire track element is embodied in a single piece of plastics formed in plane configuration and it is then rendered three-dimensional by insertion of spacers.

1 . A track element for composing a track of the fall type for run of marbles, comprising a guide member for the insertion of marbles, intended to be placed beneath the arrival of a preceding track element or at the upper start point of a track, an exit guide member for the marbles, intended to be placed at a level lower than the level of the insertion guide member and generally over the start end of a subsequent track element, and a track section extending in the form of a pair of rails from said insertion guide member to said exit guide member, by following at least in part a helicoidal trajectory.  
     
     
         2 . A track element as set forth in  claim 1 , wherein said track section in the form of a pair of rails which follows at least in part a helicoidal trajectory has an initial rectilinear section and a final helicoidal section, said initial rectilinear section serving for the approach of the marbles to said final helicoidal section.  
     
     
         3 . A track element as set forth in  claim 1 , wherein said track section extending from said insertion guide member to said exit guide member comprises a pair of rails and a number of curved sleepers which are connected from point to point to said rails, said curved sleepers having their concavity directed upwards.  
     
     
         4 . A track element as set forth in  claim 1  which, in its whole comprising said insertion guide member, said exit guide member and said track section, is manufactured as a single piece of plastic material.  
     
     
         5 . A track element as set forth in  claim 1  which, in its whole comprising said insertion guide member, said exit guide member and said track section, is manufactured as a single piece of plastic material in a substantial plane configuration, and further comprising spacers engaged in some points for imparting the correct disposition of the different portions in the height.  
     
     
         6 . A track element as set forth in  claim 1 , further comprising a pair of rails, a number of sleepers mutually connecting said rails, some of said sleepers having bottom protrusions, and a number of spacers in the form of a Z, engaged on said bottom protrusions of some sleepers.
